Salty Fins - salt water fish and coral store at 799 E. Tabernacle Street, St. George
I don't know how I missed it. My wife and I did a quick U-Turn yesterday when I saw the store while driving by on an errand. Evidently, it's been around for about 5 years.

The owner, Jan, is very personable and the livestock looked healthy. She started in the hobby when Tracy had his store, Aquarium Arts over near Albertsons in Washington. (always loved that name; Aquarium Arts).
Just a suggestion.
Referring hobbyists to the Local Fish Stores list (blue button at the left) had been my common practice until recent years. Unfortunately, with the sad closing of A Reef Oasis

the list has now become outdated to the point of being obsolete.
Aloha,
Mark

P.S.
Aquarium Arts still exists! Just found it here.
